-# Elite: Dangerous Long Range Router (Rust Version)
-
-## Usage:
-
-1. download `bodies.json` and `systemsWithCoordinates.json` from https://www.edsm.net/en/nightly-dumps/ and place them in the `dumps` folder
-2. run `cargo +nightly install --path .` or `cargo +nightly install --git https://gitlab.com/Earthnuker/ed_lrr.git`
-3. run `ed_lrr_pp --bodies dumps/bodies.json --systems dumps/systemsWithCoordinates.json`
-    - Alternatively run `process.py` in the `dumps` folder
-4. run `ed_lrr --help`
-
-
-
-## Dependencies
-
-- Working nightly Rust Compiler (tested with `rustc 1.37.0-nightly (5d8f59f4b 2019-06-04)`)
-- ~8GB of free RAM
-- Optional:
-  - Python 3.7
-  - Pandas
-  - uJSON
+# Prerequisites
+
+- Python:
+  - conda (miniconda/anaconda)
+  - tox (`conda install tox`)
+  - Inno Setup Compiler
+    - Download from [here](http://www.jrsoftware.org/isdl.php)
+    - or install via [scoop](https://scoop.sh/) `scoop install inno-setup`)
+- Visual Studio 2019
+- nightly rust compiler (`x86_64-pc-windows-msvc`)
+
+# Building an installer
+
+(Assuming `conda` is in your `PATH`)
+
+1. Start a Visual Studio 2019 x64 command prompt
+2. Run `tox`
+3. Grab the installer from `installer/Output/`
+
+# Installing
+
+(Assuming `conda` is in your `PATH`)
+
+1. Start a Visual Studio 2019 x64 command prompt
+2. Run the following commands:

+| --------- | ------------------------------------------------------------ |
+| id        | unique ID-Number (not equal to id or id64, just a sequential number) |

+| system    | Name of System                                               |
+| body      | Name of Star                                                 |
+| mult      | Jump Range Multiplier (1.5 for White Dwarfs, 4.0 for Neutron Stars) |
+| distance  | Distance from arrival in Ls                                  |
+| x,y,z     | Position in Galactic Coordinates with Sol at (0,0,0)         |
+
+## `stars.idx` format
+
+`bincode` serialized data:
+
+- **[u64]**: List of byte offset for records (entry 0=first recod, entry 1= second record, etc)
+
+## Routing Algorithms
+
+### Breadth-First Search (BFS)
+
+Standard Breadth-First Search, always finds the shortest route
+
+### A*-Search
+
+Modified A*-Search with adjustable "greediness". Priority Queue weighted by $\text{number of jumps from start system} + (\text{estimated number of jumps to target system} * \text{greediness})$
+
+A greediness of 0 is equivalent to BFS and a greediness of $\infty$ is equivalent to Greedy-Search
+
+### Greedy-Search
+
+Priority Queue weighted by minimum distance to target, prefers systems with high multiplier (Neutron Stars and White Dwarfs)
+
+## Optimizations
+
+### Ellipse elimination
+
+Only consider systems within an ellipsoid with source and destination as the foci, the width of the ellipsoid is adjustable
+
+## Routing Graphs
+
+### File format
+
+`bincode` serialized data:
+
+- *bool* **primary**: flag to indicate that graph only includes primary stars
+- *f32* **range**: jump range for routing graph
+- *[u8]* **file_hash**: sha3 hash of `stars.csv` from which graph was generated
+- *String* **path**: path to `stars.csv` from which graph was generated
+- *FnvHashMap* **graph**: Hashmap mapping systems to the systems from which they can be rached, traversed from destination system backwards to source to reconstruct route
+
+# Usage

+<!--
+TODO: Add screenshots
